Genus Mortoniella

This genus has been treated comprehensively for the neotropics in a series of revisions by Blahnik and Holzenthal (2008, 2011, 2017). The reader is referred to the last of these publications for a discussion of the terminology used here and illustrations of structures. The two new species from Panama fall within the “florica subgroup” of the leroda group, as originally defined by Blahnik and Holzenthal (2008). The subgroup was subsequently merged within the leroda subgroup ( Blahnik and Holzenthal 2017), due to uncertainty about the monophyly of the latter group as originally defined. The two subgroups represent the majority of the species of Mortoniella in Central America. Species assigned to the “florica subgroup” are characterized by paired, rounded dorsolateral projections on the phallicata, as well as paired apicoventral projections on the fused inferior appendages and a prominent apicoventral spine on the endophallic membrane.
